Nice work, Alfred. This is actually a good reference image for when I try a close-up with my PST etalon.

Good result. Etalon looks slightly red to me.

Hi Mark,

I struggle with setting a "right tilt". Hence I am not surprised if it was off-band. Can you teach me how to tell that the etalon has been tuned beyond 656.28nm into the red?

Thanks.
